Connections
Connections to the AdderLink XD522 units do not need to be carried out i\
n the 
order given within this guide, however, where possible connect the power in as 
a final step.
Transmitter
Video connections
Video connections are made between the host computer and the two 
DisplayPort sockets on the rear panel of the transmitter unit.    
To connect the video ports
1 Use the supplied DisplayPort video cable to link DP port 1 on the rear p\
anel 
of the transmitter unit with the primary video output socket of the host\
 
computer. 
From the host computer’s  secondary DisplayPort video output 
From the host computer’s  primary DisplayPort video output 
2 If a second video display is required, use an additional DisplayPort vid\
eo 
cable (Adder part number: VSCD10) to link DP port 2 on the rear panel \
of 
the transmitter unit with the secondary video output socket of the host \
computer. 
USB connections
USB connections are made between the host computer and the two sockets o\
n 
the rear panel of the transmitter unit, labeled Link A and Link B. 
Link A provides low/full speed USB to the three USB ports (all labeled \
A) that are 
located on the front panel of the AdderLink XD522 receiver. The optional\
 Link B 
provides Hi-Speed USB to the single USB port (labeled B) that is also \
located on 
the front panel of the AdderLink XD522 receiver.  
From USB sockets on the host computer 
Note: Low/full speed USB devices can also be used on port B; the transfe\
r speed 
will be automatically reduced. The A ports support USB keyboards and mice only.  
To connect the USB ports
1 Use one of the supplied USB cables to connect the Link A socket on the 
rear panel of the transmitter unit with a vacant USB socket on the host \
computer.
2 If the USB port B is required (on the receiver unit), use the second s\
upplied 
USB cable to connect the Link B socket on the rear panel of the transmit\
ter 
unit with a vacant USB socket (v2.0) on the host computer.

Audio connections
The AdderLink XD522 units support analog and digital audio. Line in and \
line out connectors are provided on both the transmitter and receiver un\
its. 
Additionally, the receiver has dedicated headphone and microphone jacks \
on its 
front panel.   
The Line In  socket on the transmitter and the Line Out  socket on the 
receiver are dual purpose. They can accept either 3.5mm analog jacks or \
mini-
TOSLINK optical fiber connectors. The latter provide access to the opt\
ical  
S/PDIF (Sony/Philips Digital InterFace) capabilities supported by the \
AdderLink 
XD522 system, which transmits PCM (Pulse Code Modulation) audio at 96K\
Hz. 
The digital and analog channels run independently alongside each other v\
ia the 
CATx link.
Third party adaptors (not supplied) are available to convert between t\
he 
mini-TOSLINK connections used on the AdderLink XD522 units and the more \
common full size TOSLINK connectors found on many audio/visual devices. \
        
To connect analog audio
1 Use the supplied 3.5mm jack audio cable to connect the Line In  socket 
on the transmitter to the analog Line Out or speaker socket of the host \
computer. 
From the host computer’s  Line Out or speaker socket
2 If a microphone or other audio input is required (from the AdderLink XD\
522 
receiver back to the host computer), use another 3.5mm jack audio cable\
 
to connect the Line Out  socket on the transmitter to the analog Line In 
socket of the host computer 
From the host computer’s  Line In socket
To connect digital audio
1 Use either a mini-TOSLINK fiber optic cable (or a full size TOSLINK fiber optic 
cable plus a mini-TOSLINK adaptor) to connect the Line In  socket on the 
transmitter to the digital Line Out socket of the host computer. 
TOSLINK cable from host computer plus mini-TOSLINK adaptor
Mini-TOSLINK cable from host computer
 Note: This digital input is fed across the main CATx link to the optical\
 
connection of the receiver’s Line Out socket only. There is no crosso\
ver 
between the analog and digital audio subsystems of the AdderLink XD522 
installation.

Serial connection
The Options port on the rear panel of every AdderLink XD522 unit operate\
s as a 
serial connection that can either:
•	 Be	used	to	update	the	firmware	of	the	unit	(see	Performing an upgrade 
for details), or
•	 Provide	an	RS232 serial connection that is passed between the transmitter 
and receiver.
Whenever the AdderLink XD522 units are not in upgrade mode, they are rea\
dy 
to transfer serial data between them at rates up to 115200 baud. When se\
rial 
devices are attached to the Options ports on the transmitter and receive\
r, the 
units transparently convey the signals between them - no serial config\
uration is 
required.   
To connect serial devices
1 Use the supplied serial cable to link the Options port on the rear panel\
 of the 
transmitter unit with a vacant RS232 serial port on the host computer. 
From the host computer’s  serial port
Link connections
AdderLink XD522 transmitter and receiver units are linked by either one \
or 
two CATx cables at a distance of up to 150 meters (492 feet). The type\
 and 
quality of the CATx cables used are crucial to the mode of operation (p\
lease 
see the section Tips for achieving good quality links). If Hi-Speed USB is not 
needed at the receiver then a CATx link between the B ports of the units\
 is not 
necessary.
IMPORTANT: The signals sent through the link cables are NOT compatible 
with standard networking equipment and could cause damage if 
connected. Do not connect the transmitter or receiver modules to any other 
networking devices.    
To link the units
1 Connect the CATx link cable from port A of the receiver unit to port A o\
n 
the front panel of the transmitter unit.
From link port A on the receiver unit 
From link port B on the receiver unit (required only for transfer of Hi-Speed USB) 
2 If Hi-Speed USB is required, connect the CATx link cable from port B of \
the 
receiver unit to port B on the front panel of the transmitter unit.  Please see Appendix A for pin-out details of the Options port.

Power connection
Each AdderLink XD522 unit is supplied with a 20W power adaptor. There is\
 no 
on/off switch on the unit, so operation begins as soon as a power adapto\
r is 
connected. 
To connect the power supply
1 Attach the output lead from the power adaptor 
to the 5V socket on the rear panel of the unit.
Note: Both the unit and its power supply generate heat when in operation\
 and 
will become warm to the touch. Do not enclose them or place them in loca\
tions 
where air cannot circulate to cool the equipment. Do not operate the equ\
ipment 
in ambient temperatures exceeding 40 degrees Centigrade. Do not place th\
e 
products in contact with equipment whose surface temperature exceeds 40 \
degrees Centigrade.
3 Connect the power lead to a nearby mains supply socket.
 
2 Connect the IEC connector of the supplied country-specific power lead \
to 
the socket of the power adaptor.

Receiver
Video display connections
Two DisplayPort sockets are provided on the rear panel of the transmitte\
r 
unit. When using high resolution video displays, it is important that th\
eir video 
bandwidth requirements lie within the capabilities of the DisplayPort so\
cket to 
which they are attached. The bandwidth available at the two sockets on t\
he 
receiver unit can be different and are greatly affected by the mode in w\
hich the 
AdderLink XD522 system is running. Please see Video support for details about 
high and low rate video modes and supported resolutions.
The link capacity (between transmitter and receiver) is checked period\
ically to 
determine which rate mode can be supported. Checks are generally made: W\
hen 
the units are powered up; when the main CATx link is made; if cables are\
 
disconnected or if the CATx link is lost for some other reason such as e\
lectrical 
interference. You can choose which rate mode is preferred (see Using hotkeys).
Support for other video standards
Both sockets support the DP++ (aka: DisplayPort Dual-Mode) standard, w\
hich 
means that as well as providing high resolution DisplayPort signals they\
 can also 
sense when a single-link HDMI or DVI adaptor is attached. When this occu\
rs, 
the output signals are adjusted accordingly to support those display typ\
es. 
Additionally, a (more complex) dual-link DVI adaptor can be attached (\
to port 
1 only), which provides higher resolution signals for special DVI displ\
ays. Some 
adaptors use power from the video socket whereas others require an exter\
nal 
power supply and this is usually gained from a spare USB socket. Port 1 \
can 
provide a higher bandwidth than port 2 (which is limited to a maximum o\
f 
154Mpixels/per second). Single-link DVI can require up to 165Mpixels/per second.
To connect the video ports
1 Connect the DisplayPort video cable from the primary video display to th\
e 
DP++ port 1 on the rear panel of the transmitter unit.
 If an adaptor is being used to convert signals, connect it to the DP++ port 1 
and connect the cable from the video display to the output of the adapto\
r. If 
an externally powered adaptor is required, you may need to also connect \
it 
to one of the USB ports in order to derive its power.
From the primary video display 
From the secondary video display (if used) 
2 If a second video display is to be used, connect its cable to the DP++ p\
ort 
2 on the rear panel of the transmitter unit. If an adaptor is required, \
see 
above. 
 Note: Although port 2 supports DP++ dual-mode operation, it is limited t\
o 
154Mpixels/sec (when the AdderLink XD522 units are running in high rate\
 
mode). Some single-link video connections require up to 165Mpixels/sec.\
EDID management
AdderLink XD522 intelligently manages the EDID (Extended Display Identification 
Data) information that each video display provides (detailing their su\
pported 
resolutions) before reporting them to the host PC. In this way AdderLin\
k XD522 
can mask the resolution modes that cannot be supported within the availa\
ble 
bandwidth. The display attached to Video port 1 will always be given pri\
ority. If 
sufficient bandwidth does not exist for the modes declared by the seco\
nd display, 
then it will not be reported to the host PC. EDID information is checked\
 whenever 
a new monitor connection is sensed whereupon it is passed to the PC.
